I didnt want to spend on a heater because the whole point of our pool is to try to keep the costs almost to 0 so we just have a pool person come 1 or 2 times week we dont turn on the filter rather clean the pool and have the pool person use his portable filterpump to filter our pool a bit

Warmed the pool right up easy to cut to shape fit perfectly perfect cover we have a small pool in our house it used to be an old school big diving pool with two depths with a trampoline but we remodeled it into a small chillingpool with just one depth and it ends up having around 10000 gallons
